struct in UnityEngine.Rendering
/
Implemented in:UnityEngine.CoreModule
Parameters you can use to configure ray tracing triangle geometry instances that are part of a RayTracingAccelerationStructure.
The triangle geometry is specified using GraphicsBuffers containing vertex and index data and additional parameters.
| Property | Description |
|---|---|
| accelerationStructureBuildFlags | The flags Unity uses when it builds the acceleration structure for the geometry referenced by this ray tracing instance configuration. |
| accelerationStructureBuildFlagsOverride | Whether to override the build flags specified when creating a RayTracingAccelerationStructure. |
| dynamicGeometry | Whether Unity considers the geometry animated or not. |
| enableTriangleCulling | Whether front/back face culling for this ray tracing instance is enabled. |
| frontTriangleCounterClockwise | Whether to flip the way triangles face in this ray tracing instance. |
| indexBuffer | The index buffer that Unity uses to define the ray tracing geometry instance. |
| indexCount | The amount of indices from indexBuffer that defines this ray tracing geometry instance. |
| indexStart | The first index from indexBuffer that defines this ray tracing geometry instance. |
| layer | The Layer used by the ray tracing instance. |
| lightProbeProxyVolume | The LightProbeProxyVolume the ray tracing instance uses. |
| lightProbeUsage | The Light probe interpolation type for this instance. |
| mask | The ray tracing instance mask. |
| material | The Material the ray tracing instance uses. |
| materialProperties | Additional Material properties to apply onto Material. |
| motionVectorMode | Motion vector mode. |
| renderingLayerMask | A mask that you can access in HLSL with unity_RenderingLayer built-in shader uniform. |
| subMeshFlags | Flags that determine the ray-geometry intersection behavior relative to Material type during ray tracing. |
| vertexAttributes | An array of vertex attributes that define the vertex format of vertexBuffer. |
| vertexBuffer | The vertex buffer that Unity uses to define the ray tracing geometry instance. |
| vertexCount | The amount of vertices from vertexBuffer that defines this ray tracing geometry instance. |
| vertexStart | The index of the first vertex from vertexBuffer that defines this ray tracing geometry instance. |
